Embryonic organizers or organizing centers are cells located in certain regions of the embryo coordinating morphogenesis which communicate with each other "via a network of secreted signaling proteins, such as bone morphogenetic proteins and their antagonists (chordin and noggin)."

Role in the morphogenetic singularity theory
For more details, see morphogenetic singularity theory
- Organizing centers have high electrical conductance and current density
- Organizing centers have high density of gap junctions
- At the macroscopic level, organizing centers are singular points in the morphogen gradient and electric field
These predictions, formulated by the author of the hypothesis, Charles Shang, from the Emory University School of Medicine (and formerly from the Department of Biochemistry and Molecular Biology of Harvard University) were later verified. Shang proposes that acupuncture points originate from organizers.
